Arundic Acid is an astrocyte-modulating agent, delays the expansion of cerebral infarcts by modulating the activation of astrocytes through inhibition of S-100β synthesis.

5-Hydroxymethyluracil is an oxidation damage product derived from thymine or 5-methylcytosine. It is a product of thymine dioxygenase. Additional deamination products such as 5-hydroxymethyluracil are formed when cells are under oxidative stress that is induced either by oxidizing agents or by mitochondrial dysfunction.
